I have a nanny watching my son and we love her. I trust her 100%. Sh erecently got a driver's license and it is possible that when the weather is cold, she may need to meet me at the train with my son (only a mile away) if my train is running late so that she can catch her train home. Although I trust her, there is a part of me that HAS to check it out. Anyone know of a reputable way to check??
